Method for the non-bitrate-dependent encoding of digital signals on a bus system

Abstract

To provide a bus system having a plurality of stations that are coupled together by an arrangement of lines and each have a transceiver and a control unit, a microcontroller, or the like, and to specify a method of encoding a digital message on a bus system in which method the digital message comprises at least one part that is encoded in a non-bitratedependent manner and by means of which method it becomes possible for a transceiver or a system base chip to independently receive and analyze the data transmitted on the bus line, and in particular, in accordance with the method, to individually wake a bus node by means of a given wake-up message even when the part of the bus node that is on standby at the relevant point in time does not have an accurate timer and also does not have any knowledge of the bitrate at which the data is transmitted on the bus, provision is made, under the bus system according to the invention, for at least one transceiver (100) to comprise means for the non-bitrate-dependent analysis of digital signals and, under the method according to the invention, for the value of a bit in that part of the message that is encoded in a non-bitratedependent manner to be represented by the lengths of successive dominant and recessive phases.
